Abstract
The duration of post-traumatic amnesia (PTA), which is the period foll owing brain injury when patients are disoriented and impaired in the a cquisition of new information, has been used as a behavioural indicato r of the severity of injury. This paper reviews earlier retrospective and more recently developed prospective methods of assessing the durat ion of PTA. Prospective assessment that commences before the resolutio n of PTA overcomes the possible over- or underestimation of the durati on of PTA inherent in methods that assess PTA retrospectively by clini cal interview.
